Batch conversion of CHAT files to Praat TextGrids

[Fredrik Karlsson]

Hi,

I whant to convert allt the .cha-files I downloaded from the ESF
Corpus made public through the MPI archive system. I have tried CLANS
chat2praat program, but it fails. This is the log:

> dir *.cha
cha liean11b.1.cha liean12e.1.cha liean13g.1.cha
liean14a.1.cha liean14a.2.cha liean16a.1.cha liean16k.1.cha
liean17l.1.cha liean18a.1.cha liean18c.1.cha liean22a.1.cha
liean22e.1.cha liean22g.1.cha liean23c.1.cha liean24a.1.cha
liean24i.1.cha liean25a.1.cha liean25k.1.cha liean27l.1.cha
liean31a.1.cha liean31d.1.cha liean32a.1.cha liean32e.1.cha
liean32g.1.cha liean32h.1.cha liean34q.1.cha liean35j.1.cha
test.cha unixfile.cha

chat2praat (28-Jul-2008) is conducting analyses on:
ALL speaker tiers
and those speakers' ALL dependent tiers
and ALL header tiers
****************************************
>From file <liean11a.1.cha> to file <liean11a.1.textGrid>


*** File "liean11a.1.cha": line 16.
Illegal speaker character found: 15.

CURRENT OUTPUT FILE "liean11a.1.textGrid" IS INCOMPLETE.

Line 16 of the file is:

^U%snd: "liean11a.wav" 9383 13613^U

where ^U seems to be a \x0015. Removing the character with perl

> perl -nae 's/\x15//;print'  liean11a.1.cha > test_liean11a.1.cha

makes the file not readable for CLAN:

.....
*** File "test_liean11a.1.cha": line 1481. <- Lots of messages like
this one
It is illegal to have Header Tiers '@' inside the transcript


    NO BULLETS FOUND IN THE FILE


Done with file <test_liean11a.1.textGrid>

So, what do I do? The chat2elan seems to behave the same way.

I would, or course, appreciate any help I could get.
